Abstract
The biggest challenge in the miniaturization of spectrometers is achieving high sensitivity and resolving power at reduced device dimensions. The gas-filled linear variable optical filter (LVOF) enhances the interaction between the light and the sample, thereby improving the sensitivity in a small footprint, by using the resonator cavity of a wideband interference filter also as the gas cell
in a wafer-level implementation. The demanding operating conditions of the gas-filled LVOF renders the conventional approximation of the tapered resonator into an array of Fabry-Perot filters invalid. A novel design method using the Fizeau interferometer approach is
described and demonstrated with measurements.
